Night Vision for GURPS Game Aid (GGA).
FVTT/GGA implementation of the Night Vision advantage, based on a Warhammer mod by TheFirst05, with permission.
This module partially automates the Night Vision talent in the gurps system. The effective dim illumination radius of all light sources is extended for a selected token with the Night Vision talent or trait.
The effect gets stronger with higher levels of Night Vision. For details, see the wiki page.
